Network-simulation modeling of interactions between maintenance and process systems

Network simulation modeling, which can be an important tool for reliability and maintainability (R&M) assessments, is described in some detail. As an example application, network simulation modeling is used to evaluate the adequacy of the maintenance system of a nuclear fuel processing plant. The interaction between the maintenance and chemical process systems is modeled using a Monte Carlo sampling procedure for treating failure and repair events. It is concluded in the example problem that at least two mobile manipulators and one through-the-wall manipulator are needed to maintain a facility of this particular design
